Silverl里柱状图，怎么设置Y轴信息显示在每根柱子上面
toolkitChart Chart

Chart_Myself.Series.Clear();
ColumnSeries series = new ColumnSeries();
series.ItemsSource = mCETBList;//绑定数据源集合
series.IndependentValueBinding = new System.Windows.Data.Binding("Caption");//X轴名字
series.DependentValueBinding = new System.Windows.Data.Binding("Numbers");//Y轴数量
series.Title = "上传量";
Chart_Myself.Series.Add(series);

Numbers是Y轴信息，我想让它在柱子上面显示，要怎么设置呀？？？？
